Symmetry means being made up of exactly similar parts. If your parts go around a central point, you have what kind of symmetry?

Vanyuwa [196]

Yes. Upper-layer skin cells and the cells in the front surface of the eyes get a significant amount of oxygen directly from the air rather than from the blood. Human bodies have a huge demand for oxygen. As a result, the oxygen that is able to passively diffuse into the body directly from the air is not nearly enough to run the whole body. Fortunately, we have lungs that can actively pull in oxygen and transfer it to the blood, allowing the body to transport oxygen to the cells by using the blood like a fleet of delivery trucks. Most of our cells rely on the blood delivery service. However, the cells in the outer layers or our skin and eyes are in direct contact with the atmosphere and can efficiently get their oxygen right from the air.
Yes, there are nuclear reactions constantly occurring in our bodies, but there are very few of them compared to the chemical reactions, and they do not affect our bodies much. All physical objects are made of molecules. A molecule is a series of atoms linked together by chemical (electromagnetic) bonds.
Photon wave phase can also not be directly detected by humans but can be detected by machines called interferometers. Phase information is often used to determine the flatness of a reflecting surface. In summary, humans can indeed see photons. Humans can see all of the properties of photons except for spin and wave phase.

Answer:

The answer of ist question FADH2,NADH 2nd question O2 3rd question NAD+,FAD,H2O,ATP.

Explanation:

Ist answer

During electron transport chain electrons are donated by reduced coenzymes such as NADH and FADH2.

2nd answer

During electron transport chain oxygen or O2 act as terminal electron acceptor which accepts and then undergo reduction to generate H2O.

3rd answer

The final products of electron transport chain and oxidative phosphorylation are NAD+, FAD,H2O and ATP.

The net gain of ATP molecules per molecule of glucose in the reactions of glycolysis is 2.

Glucose is the main source of almost all energy used by cells of similar and different organisms.

In glycolysis process, the production of two pyruvate molecules, a net gain of two ATP molecules, and two NADH molecules takes place.
